Although it doesn’t happen often, occasionally, an attacker breaks in to a server and manages to modify source code or binary packages that people install on their machines. This happened recently, well actually not that recently, when an attacker broke in and replaced the file Unreal3.​​2.8.1​.tar.gz with one that contains a back door in the DEBUG3_DOLOG_SYSTEM macro.
